mow before or after it rains?

It's been awhile since we seen any meaningfull rain around here. Most of my accounts still look ok but the drought is starting to take it's toll. I have a few accounts that are due today, but we should be getting a good rain tomorrow. My question is:

Should I go ahead and mow or would it be better to wait and let the rain come. Is there any benifite to cutting now of after the rain. Any ideas?

if you're in a "drought" it can be stressful to your grass to mow it right now, before rain, but it won't hurt anything to mow after the rain. Sometimes if the grass is really dry and dead or almost dead the mower breaks the blades of grass off (tires, deck rollers, stripe kits etc) and makes the lawn look nasty. If you can wait till it rains you would be better off, unless your schedule is too tight to risk losing a day or two.
Good luck,
Eric
